ICD-10 Codes MCP

Anthropic-published MCP server distributed via the anthropics/healthcare plugin marketplace. Exposes the International Classification of Diseases, 10th Revision (ICD-10) — both diagnosis (ICD-10-CM) and procedure (ICD-10-PCS) codes — for medical coding, billing accuracy, and claims management. Underlying data is published by CMS and the CDC.

   
Type MCP server
Supplier Anthropic

Pricing Free / OSS
Capabilities Read-only — code lookups and validation

How to install

  • Claude Code — plugin marketplace (recommended):

    /plugin marketplace add anthropics/healthcare
claude mcp add-from-marketplace anthropics/healthcare/icd-10-codes

  • Claude Desktop — proxy the marketplace MCP via mcp-remote if the upstream endpoint is HTTP; otherwise consult the marketplace mcp.json for the literal stdio command.

    Registration form not exhaustively documented upstream — adapt the snippet to whatever the marketplace’s mcp.json ships for this server.

What it does

Wraps ICD-10-CM and ICD-10-PCS code sets with MCP tools that let Claude:

  • Look up a diagnosis or procedure code by ICD-10 identifier.
  • Search the code set by clinical term, body system, or chapter.
  • Validate a code’s currency against the most recent CMS / CDC release.

Primary use cases: Medical coding QA, claims-validation pipelines, prior-authorization review (pairs with prior-auth-review skill and cms-coverage MCP), and reference lookup inside clinical-trial protocol drafting.

Notes

ICD-10 is the US baseline; some payers also require ICD-10-CM modifiers and external-cause codes. This MCP covers the core code set — confirm payer-specific modifier requirements separately. Does not include CPT or HCPCS — those are governed by separate code sets.
